Currently, such global data and = its > initialization functions are even scattered. Rather than 'extern'-ing suc= h > variables and calling such functions one by one making sure it is called = only > once by checking the validity of such variables, it will be better to hav= e a > global storage to hold such data and a consolidated function having all t= he > initializations. The existing shared memory gets more extensively used fo= r > this purpose. As there could be multiple secondary processes, a static > storage (local to process) is also added. >=20 > As the reserved virtual address for UAR remap is a PMD global resource, t= his > doesn't need to be stored in the device priv structure, but in the PMD gl= obal > data. >=20 > Signed-off-by: Yongseok Koh <yskoh@mellanox.com> Acked-by: Shahaf Shuler <shahafs@mellanox.com>
